c# - detecting in form1 that form2 is closed -

i trying detect form2 closed in form1. have far

    private void addstagebtn_click(object sender, eventargs e)     {         form2 form2 = new form2();         form2.showdialog();         if (form2.isdisposed)         {             messagebox.show("it closed!");         }     } 

any suggestions? again!

adhere formclosed event of form2.

wherever create do:

form2.formclosed += new formclosedeventhandler(form2_formclosed); 

then create method:

void form2_formclosed(object sender, formclosedeventargs e) {     // whatever want here } 

you'll want use .show() instead of .showdialog() if want able use either form, otherwise form1 unavailable until form2 closed (which assuming not behavior looking for).
